Spotted Lanternfly inElizabeth, NJSPOTTED LANTERNFLY GUIDE
Union County confirmed SLF in 2019. Elizabeth — New Jersey's 4th largest city — is home to two of the most significant SLF spread vectors on the East Coast: Newark Liberty International Airport and Port Newark-Elizabeth Marine Terminal, the largest container port on the East Coast. Wooden shipping pallets at Port Elizabeth are a primary SLF egg mass transport mechanism, and air cargo at EWR presents unique long-distance dispersal risk. The Northeast Corridor rail line running through downtown connects Elizabeth to the broader mid-Atlantic infestation corridor.

Tree of Heaven in Elizabeth, NJ
Port Elizabeth's industrial waterfront is the highest-risk SLF freight pallet zone on the East Coast — shipping containers and wooden pallets arriving at the Port Newark-Elizabeth Marine Terminal represent a continuous SLF introduction and dispersal vector. Newark Airport perimeter vegetation includes established Tree of Heaven. Warinanco Park and the Arthur Kill waterway corridor provide additional TOH habitat supporting SLF colonies throughout Union County. Elizabeth's position as a freight and transit hub makes it one of the most consequential SLF nodes in New Jersey.
